What It Is

A 90° corner post formed from 100 mm C‑section galvanized steel, engineered specifically to create strong, structural corners in concrete sleeper retaining walls. This post serves as both a supporting element and corner junction point in your wall system. 

Key Features

  • Galvanized 100 mm C‑Section Steel: Hot-dipped galvanization provides strong corrosion resistance for outdoor exposure.
  • Precision 90° Profile: Factory-formed right-angle post ensures clean, accurate corner alignment. 
  • Compatible with Sleeper Systems: Designed to securely accommodate concrete sleepers in C-channel grooves.
  • Durable & Load‑Bearing: Engineered to manage corner loads and soil pressure in retaining walls.

Benefits

  • Robust Corner Support: Provides the structural backbone for stable, long-lasting 90° wall corners.
  • Easy Installation: Pre-formed angle ensures precise alignment without on-site bending or welding.
  • Corrosion‑Resistant & Weather‑Proof: Galvanization extends service life in outdoor landscaping.
  • Seamless Integration: Works with standard 100 mm sleeper systems—stack, stagger, and secure smoothly.

Landscape Ideas

  • L-Shaped Retaining Walls: Use this corner post to execute neat, strong L-shaped wall designs.
  • Terraced Garden Designs: Combine with straight posts to frame multi-level bed structures.
  • Defined Patio Edges: Create structured corner edges for patios or pathways with clear demarcation.
  • Outdoor Step Features: Integrate into step-retaining walls, providing corner strength and aesthetic cut.

How to Use It

  1. Prepare a compacted footing or pad at the corner location.
  2. Position the corner post vertically and embed in concrete (minimum depth based on wall height).
  3. Align adjacent straight C‑section posts as per wall runs.
  4. Slot concrete sleepers into the C-channel grooves, staggering joints for strength.
  5. Backfill with drainage aggregate and install geotextile as per best practice.

Coverage Example

  • Each corner post secures the junction of two wall sections.

  • For a U‑shaped wall, use two 90° corner posts (one left, one right) to define both ends.
